EVAL6470PD STMicroelectronics

EVAL6470PD Fully integrated stepper motor driver mounting the L6470 in a high power PowerSo package Data brief Description The EVAL6470PD demonstration board is a fully integrated microstepping motor driver. In combination with the STEVAL-PCC009V2 communication board and SPIN evaluation software, the board allows the engineer to investigate all the features of the L6470 device. In particular, the board can be used to check the voltage mode driving and to regulate the L6470 parameters in order to fit the application requirements. The 4-layer layout and the PowerSO package allow the top thermal performance to be obtained. The EVAL6470PD supports the daisy chain configuration making it suitable for the evaluation of the L6470 in multi motor applications. AM11329v1 Features Voltage range from 8 V to 45 V Phase current up to 3 A r.m.s. Dual SPI connector (daisy chain configuration suitable) SW input FLAG and BUSY LED indicators Adjustable supply voltage compensation High thermal performance (R 12 C/W thj-a typical) Suitable for use in combination with the STEVAL-PCC009V2 March 2015 DocID022606 Rev 3 1/11 For further information contact your local STMicroelectronics sales office. www.st.comBoard description EVAL6470PD Board description Table 1.
